Abstract
The invention is directed to a wet end assembly disposed at a wet end of a paper making machine for forming a fiber web from a fiber suspension. A headbox including a plurality of inner walls defines a chamber. The headbox further includes an inlet in communication with the chamber for receiving the fiber suspension and a discharge nozzle in communication with the chamber for discharging the fiber suspension. The headbox further includes structure, engaged with the inner walls, for selectively and adjustably compensating for deflections of the inner walls. A former includes a moving top endless wire and a moving bottom endless wire, with the top endless wire and the bottom endless wire defining a converging gap therebetween. The converging gap has an entrance end positioned adjacent the discharge nozzle for receiving the fiber suspension therefrom. A press section includes a suction roll carrying an endless belt. The suction roll is positioned adjacent the top endless wire whereby the fiber suspension is transferred from a bottom of the top endless wire to a top of the endless belt.
